which one of the plants pictured below was given water mixed with salt, and which one was given pure water? Explain how you know
ludmilkaskok [199]

The plant on the right must have been the one given a saltwater mixture while the one on the left must have been given pure water.

<h3>Osmosis</h3>

Looking at the attached image closely, one would see that the plant on the right has withered leaves while the leaves of the plant on the left seem to be flourishing.

The plant on the right must have been the one fed with water mixed with salt and here is the reason. Adding water mixed with salt to the soil on which the plant grows will decrease the water potential of the soil relative to the water potential of the plant's root. Thus, water will move from the plant into the soil through the root by osmosis. This will cause the various cells of the plant to become flaccid, and hence, the withered leaves.

On the contrary, the plant on the left must have been fed with pure water. Feeding the soil with pure water will increase the water potential of the soil relative to the water potential of the plant's root. Thus, water will move from the soil into the plant through the root by osmosis. This will cause the various cells of the plant to become turgid, and hence, the flourishing leaves.

Select the correct answer from each drop-down menu. the sun is the primary source of energy for ecosystems. the sun emits . when
galben [10]

The scientific law of one organism feeding off other where energy is transferred from one form to another is known as the law of conservation of energy.

<h3>How the sun is the primary source of energy for ecosystems?</h3>

Energy from the highest energy source that is sun is absorbed by plants to convert it into food (i.e a form of energy). plants are the only ones that can convert sunlight into another form of energy directly.

The animals and organisms that feed off of the plants take some part of this energy for their life cycles and then the animals that feed off of these animals again take some part of this energy and carry on with their life cycle, this is how energy from sun (highest source) is transferred to different organisms by Just changing form.

Thus, The scientific law of one organism feeding off other where energy is transferred.

Margarita [4]

<u><em>If wrinkled seeds are dominant, it is a 75% chance, if round seeds are dominant, it is a 25% chance. In this case it's probably 25%, considering round seeds are emphasized.</em></u>
